Watch the video to the right as you take/re-take notes in your notebook.

Low Pressure System Weather

• Air moves into a low pressure system. Since there is no where else for the air to go, it rises.

  
  

• We know from our cloud formation notes that rising air leads to cloud formation.

  
  

• Low pressure systems are associated with cloudy weather.

High Pressure System Weather

• Air moves out of a high pressure system. As air moves away, air from above falls to take its place.

  
  

• Instead of RISE, EXPAND, COOL, CONDENSE, we have FALL, COMPRESS, WARM, EVAPORATE.

  
  

• High pressure systems are associated with clear skies.
